ANSWER ASAP!

-1 and -7

Step-by-step explanation:

+8x + 7

(x+1)(x+7)

x+1 = 0

x= -1

x+7 = 0

x= -7

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

i think the amount would be $140.62
